actually that's how i interpreted the question to be since it wasn't clearly written. This is exactly how i saw it written down:

So is there any way that the above question can be "interpreted" to give one of the 4 responses mentioned previously?

The only answers I can see are 1 and 1/2. Putting it into Maple confirms, as well as another way funky answer. None of these are of course a choice. Something tells me the problem might be written down wrong?
